Based on motor efficiency, flow and pressure required for 30 rpm & 250 in-lb torque? Will motor operate smooth below 30 rpm? Permissible back pressure?
A: Due to the nature of the valving inherent to geroler type motors and internal slippage in general, operation under 1.5-1 gpm is not recommended. (This motor would only take .61 gpm for 30 rpm) It may be best to use a higher flow with a larger displacement motor to achieve the correct rpm range.
